Yangyin Yiqi Mixture Ameliorates Bleomycin-Induced Pulmonary Fibrosis in Rats through Inhibiting TGF-1/Smad Pathway and Epithelial to Mesenchymal Transition

Objective. The aim of the current study was to investigate the protective effect of Yangyin Yiqi Mixture (YYYQ) on Bleomycin-induced pulmonary fibrosis in rats based on TGF-β1/Smad signal pathway and epithelial to mesenchymal transition (EMT). Methods. 120 Wistar rats were randomly divided into six groups: control group, BLM group, BLM
